This page contains information about the current configuration of EOS-BPM such as motor positions and camera orientations. Please update confluence if any of these change. This page is current as of March 12th, 2024
Crystals:
Name | Crystal Type | Location | ND Filters | Camera Orientation | Current Status |
---|---|---|---|---|---|
EOS1 | 100um GaP | Toward Walkway (South) | ND4 | Left on Image = Toward Beam (North), Right on Image = Away from Beam (South) | Aligned |
EOS2 | 100um GaP | Toward Wall (North) | ND4 | Left on Image = Away from Beam (North), Right on Image = Towards the Beam (South), Burn spot near the edge | Aligned |
Motors:
Name | ??? | Purpose | Location | Rack | Notes |
---|---|---|---|---|---|
E7 EOS Delay | XPS:LI20:MC02:M5 | Probe laser delay stage. | IP Table | FKG20-27 | Negative adds path |
EOS Flipper | Inserts or removes an ND2 Filter from the probe laser path before the PB. | IP Table | |||
E3 EOS Rotation 1 | XPS:LI20:MC04:M8 | Rotates the polarizer that cleans up the polarization of the probe before entering the PB. | IP Table | FKG20-26 | Currently at 26 |
PB4 EOS Assembly Removal | XPS:LI20:MC04:M4 | Inserts and removes EOS-BPM from the path of the beam inside the picnic basket. | PB | FKG20-26 | Removed = 50 Inserted = 10.7 At 6.5 Crystal Spacing, Range is 10.1-12.6 and middle is 11.35 Bigger value: assembly moves north |
PB29 EOS Mirror Adjustment | MOTR:LI20:MC05:S5:CH4:MOTOR | Changes the time delay of EOS2 relative to EOS2 and changes the laser position on EOS2. | PB | ??? | |
PB5 EOS Crystal Spacing | XPS:LI20:MC04:M5 | Changes the spacing between the crystals by moving EOS2 towards the wall. | PB | FKG20-26 | 8 = Closest Together (Nearly Touching) 0 = Furthest Apart |
E5 EOS1 Camera Rotation 3 | XPS:LI20:MC02:M8 | Rotation of the polarizer before the EOS1 camera. | IP Table | FKG20-27 | Extinction = 112 |
E6 EOS2 Camera Rotation 4 | XPS:LI20:MC04:M7 | Rotation of the polarizer before the EOS2 camera. | IP Table | FKG20-26 | Extinction = 150 |
E1 EOS1 Translation 1 | XPS:LI20:MC03:M8 | Stage that moves EOS1 forward or back to make sure the crystal is properly imaged onto the camera. | IP Table | FKG20-26 | |
E2 EOS2 Translation 2 | XPS:LI20:MC02:M4 | Stage that moves EOS2 forward or back to make sure the crystal is properly imaged onto the camera. | IP Table | FKG20-27 |
